Product Info

General Description

The TUA6034, TUA6036 ’TAIFUN’ device combines a mixer-oscillator block with a

digitally programmable phase locked loop (PLL) for use in TV and VCR tuners and in set-

top-box applications.

Features

General

• Suitable for PAL, NTSC, DVB and

ATSC

• Wideband AGC detector for internal

tuner AGC

− 5 programmable take-over points

− 2 programmable time constants

• Low phase noise

• Full ESD protection

• Qualified according to JEDEC for

consumer applications

Mixer/Oscillator

• High impedance mixer input

(common emitter) for LOW band

• Low impedance mixer input

(common base) for MID band

• Low impedance mixer input

(common base) for HIGH band

• 2 pin oscillator for LOW band

• 2 pin oscillator for MID band

• 4 pin oscillator for HIGH band

IF-Amplifier

• 4 IF pins to connect a 2 pole bandpass

• Symmetrical IF preamplifier with low

output impedance able to drive a

compensated SAW filter (500Ω//40pF)

PLL

• 4 independent I2C addresses

• I2C bus protocol compatible with 3.3 V

and 5V micro-controllers up to 400 kHz

• High voltage VCO tuning output

• 4 PNP ports

• 1 NPN port/ADC input

• Internal LOW/MID/HIGH band switch

• Bus controlled power down mode

• Lock-in flag

• 6 programmable reference divider

ratios (24, 28, 32, 64, 80, 128)

• 4 programmable charge pump currents

Application

• The IC is suitable for PAL, NTSC,

DVB-C, DVB-T, ISDB-T and ATSC

tuners. The focus is on digital

terrestrial.

• The AGC stage makes the tuner AGC

independent of the Video-IF AGC
